In this operating mode you can move the actuator with the decrement
(
) and increment keys ( ) and the current position is held
regardless of the setpoint current and any leakages.
.
NOTE
You can move the actuator quickly by pressing the other direction key
additionally whilst keeping the direction key selected first pressed.
The manual mode can be reported by outputting a parameterizable
fault message, a position feedback or output of limit values A1 and A2
is only possible in automatic mode.
.
NOTE
The positioner switches over to automatic mode automatically after an
electrical power failure.
The automatic mode is the normal mode. In this mode the positioner
compares the setpoint current with the current position and moves the
actuator until the control deviation reaches the parameterizable dead
zone. Error messages are output if this is not possible for various
reasons.
In this operating mode you can have the current operating data (such
as number of strokes, number of changes in direction, number of faults
messages, etc.) displayed (see table 3-1, page 91).
From the automatic or manual mode you go to the diagnostic display
by simultaneously pressing all three keys for at least two seconds.
See chapter 4.5, page 90 for further information.
.
NOTE
The respective operating mode (MAN or AUT) of the positioner is retai-
ned when you switch to the diagnostic display, i.e. in automatic opera-
tion the specified setpoint is still used for controlling and in manual
operation the position last reached is retained.
4.4 Parameters
All the parameters of the positioner are listed in this chapter. Figure 4-6
shows an overview of the parameters.
The parameter name is shown once in plain text and once as it ap-
pears in the display. The function of the parameter is described briefly
in the ”Function” column. In addition, the possible parameter values,
the physical unit and the factory setting of the parameters are shown.
